I moved the Blackstar back up a couple inches. I also question if I wasn't giving more water than needed and did not water yesterday and will refrain today as well and then give a good flush tomorrow. Given the curl down, esp with the widow, has not improved I thought this would be a good course of action. No discoloration other than they are a dark shade of green. from what I have read that could be an indication of to much N...the flush tomorrow will hopefully tell more.
